Christine O'Donnell considers reality show

The Tea Party favorite who might have cost Republicans a Senate seat won't rule out another run for office.

Christine O'Donnell won't rule out making another run for office. The former Delaware Senate candidate told Jay Leno during an appearance on the "Tonight Show" on Wednesday that she wants to keep her options open.

"I don't know if I'd run again," she said. "I'd like to keep that option open."

For the time being, O'Donnell said she wanted to remain in politics as an issue advocate. "Whatever I do, I want to be able to advocate for those issues," she said.

O'Donnell mentioned ending the estate tax, which is set to kick in at a high rate in 2011, as one issue she is interested in.  

But she has been getting job offers since her Senate bid failed.

"The offers have been interesting," O'Donnell said. "Anything from a book deal to a reality show."

She was "not necessarily interested" in the reality show offer unless it was a "watchdog-type show," she said, noting she ran a 30-minute TV ad during the campaign. "I would like to do something like that."

Leno suggested she become a Fox News pundit.

O'Donnell said she "did the pundit thing."

"That's what got me in trouble," she added.

Leno asked if she regretted her comments, which became political fodder during the campaign.

"I regret that they overshadowed what I was saying on the campaign trail," she said. "It was difficult to get my current message heard."

Earlier during the interview, O'Donnell said she initially considered appearing on "Real Time With Bill Maher" — before he released the famous clip of her saying she "dabbled into witchcraft."

"I wanted to do the show, we just couldn't get it worked out," she said.

But when she heard Maher's threat to release more clips of her appearances on his former show, "Politically Incorrect," she decided against it. "Whether it's a comedian or a terrorist, you should not respond to threats," she said.

O'Donnell was defeated in the Senate race in Delaware by Democrat Chris Coons. She beat Rep. Mike Castle (R-Del.) in the GOP primary after Castle had been the favorite to take Vice President Joe Biden's old Senate seat.
